HAY STACKER ANI) LOADER.

maris.

To all whom t may concern:

Be it known that I, LEROY It. SI-IAFTO, a citizen of the United States,residing at Elm Creek, in the county of Buffalo and State of Nebraska,have invented a new and useful I-Iay Stacker and Loader; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention pertains to a new and useful hay stacker or loader andthe object of the invention is the provision of a fork, which when beingraised increases in speed, or in other words the fork is variable in itsmovements, while the pull thereon is constant.

A further object of the invention is the production of a plurality ofcoperating movable beams, and a base portion, and which are adjustablewith regard to one another, in order to regulate the throw of the fork,when the same is being raised.

A further object of the invention is the provision of means foradjusting the inclination of the fork with regard to one of the beams.

Another object of the invention is to provide inclined members carriedby one end of the base, with which the fork may Contact, in order toallow the fork to escape the ends of the base.

In this specification and the drawings accompanying the same, a certaindesign of device is complied with, but the invention is not to beconfined to this special form. The device in its actual reduction topractice may require changes and variations; the right thereto belongsto the applicant provided such changes and variations are comprehendedby the accompanying claims.

Further objects and combination of varous parts will be hereinafter moreclearly set forth and pointed out in the appended claims.

In the drawings Figure 1 is a perspective view of the hay stacker orloader, showing the fork in its lowermost position. Fig. 2 is aperspective view of the stacker, showing the fork at its raised or itsuppermost position. Fig. 3 is a side elevation of the stacker, showingthe plurality of coperating beams adjusted in different positions,showing the fork at a different height than Specification of LettersPatent.

that shown in Fig. 2, and further disclosing the fork in dotted lines ata position between the lowermost and uppermost positions. Fig. 4t is a.view showing the hay stacker or loader folded. Figs. 5 and G aredetailed sectional views in order to further show the detailed structureof the stacker.

In regard to the annexed illustrations, 1 designates a base, composed oftwo longitudinal parallel beams 2, which are braced by transverse beams3, at each end thereof. Adjacent each end of the beams 2, they areprovided with apertures 4 and 5.

6 denotes a frame composed of two beams 7 and S, which are arranged sothat the upper ends converge to an apex or point, designated by thenumeral 9, and which is pivoted between two beams 10 and 11. The lowerends of the beams 7 and 8 are provided with apertures 12, through whichapertures t of the base bolts or elongated rods 13, penetrate. Upon thethreaded ends of the rods or bolts 13 nuts 14 are secured, in order tohold the bolts in place. By means of the plurality of apertures 4 andthe bolts 13 and nuts 1st the beams 7 and 8 may be adjusted with regardto the base.

15 denotes two parallel arranged beams, their lower ends provided withapertures 16 through which and the apertures a bolt 17 extends, and uponits threaded end a nut 1S is applied. It is clearly evident that byremoving the bolt 17 and adjusting the beams 15 with regard to the otherapertures after reinserting the bolt, the beams 15 are adjusted. Thebeams 15 and the beams 10 and 11 are made adjustable with regard to oneanother by means of a bolt and nuts 19 and 20, which coperate with theapertures 21 and 22 of said beams. The beams 10 and 11 are braced by therods 23 and 24, which are disposed angnlarly with relation to the saidbeams.

Pivoted to the lower ends of the beams 10 and 11 is the fork 25, whichis composed of forks 26 and 27, extended at right angles to one another.The fork is provided with a rearwardly extending arm 27a. This arm 27ais provided with apertures 28 in any one of which the rod 2S) may beadjusted. This rod 29 is pivoted between the beams 7 and S, slightlybelow the pivot of said beams and the beams 10 and 11. It will beunderstood that by adjusting the rod 29 in any one of the apertures ofsaid arm, the fork will be disposed at various angles as it is raised,because of the connection between the rod 29 and the beams 7 and 8. Thatis, if the rod 29 is engaging the aperture nearest the rear portion ofthe fork, the fork will be disposed at a different angle as it raises,when the beams 7 and S are being t-ilted rearwardly, than if the rod 29was inserted in an aperture farther away from the rear portion of thefork. One end of the base is provided with inclined members 30 withwhich the rear portion of the fork engages in order to prevent the forkfrom striking the end 3l of the base.

Attached to an eye 32 (which is carried by the upper end of the beams l0and ll) is a rope or cable 33. This rope or cable passes under a pulley3i, which is carried by one of the transverse beams 3. Attached to theend of the rope or cable is a swingletree 36, to which a horse (by meansof traces not shown) may be connected, in order to impart movement tothe beams 7, S, 10, ll and l5. By impart-ing a pulling action upon thecable or rope, the beams l5 are tilted upwardly upon their pivots, whilethe beams 7 and 8 are tilted downwardly, in the positions shown in F ig.2. By tilting the beams 7 and S and l5 in this manner, the beams 10 andl1 are so operated as to absolutely reverse their positions, as clearlydisclosed in Fig. 2. By reversing the position of the beams 10 and l1,the fork is raised. Vhen the beams l5 rise to the end of their movementsthey are disposed approximately in a vertical position, in whichposition they are limited by means of the cable 36. This cable 36 isconnected to the beams l5 as shown at 37, while the end 3S thereof issecured to a coil spring 39, which in turn is fastened to one of thetransverse beams 3. As the beams 15 are limited in their movements, theyare slightly vibrated through the action of the spring 39.

Having thus fully set forth the invention, what is claimed as new anduseful is l. In a hay stacker or loader, a base, having at one endforward pivoted beams, while at the other rearward pivoted beams, aforlcarrying frame pivoted to the ends of the forward and rearwardbeams, means whereby a pulling action may be exerted upon thefork-carrying frame in order to impart a variable movement to the fork,means arranged between the fork and the forward beam whereby the angleof the fork may be changed when being raised, means to prevent the rearportion of the fork from striking the base as it is raised, and means tolimit the upwardly tilting action of the angularly arranged beams.

2. in a hay stacker, a base, beams pivoted to the rear end of the base,beams pivoted to the front end of the base, a fork carrying framepivoted to the ends of the beams, the front beams being connected witht-he rear of the frame and the rear beams being connected with the frontof the frame, a forlr pivoted on the frame, a rod pivoted to the forkand the upper end of the front beams, and means for raising the forkwith the frame.
